Approved Coolant
Beginning March 14, 2016, this unit was filled with red coolant meeting Deutz
®
DQC CB-14 before
shipment from factory. Add or replace only with coolant meeting this specification. This coolant is available,
pre-diluted, from your Ditch Witch
®
dealer as part number 255-1053. Contact your Deutz service partner
for a full list of approved coolants meeting DQC CB-14. In an emergency, non-Deutz approved, heavy duty
diesel engine coolant meeting ASTM D6210 may be used. Change to DQC CB-14 coolant as soon as
practical.
Prior to March 14, 2016, this unit was filled with yellow John Deere
®
Cool-Gard
®
coolant before shipment
from factory. Add only John Deere Cool-Gard (p/n 255-006) or any fully-formulated, ethylene glycol based,
low-silicate, heavy-duty diesel engine coolant meeting ASTM specification D6210. Switch to the new
approved red coolant described above at the next change interval.

NOTICE:
• Use only pre-diluted or concentrated coolant mixed with distilled water. Do not use tap water.

premature engine failure.
